See attached patch. It also fixes the same problem for the "Category" 
view. Testing shows that the problem only affects the display of the 
version number as the solver later silently removes such install requests.

I dropped this idea and aligned Ctrl+I behavior with "Install" from 
"Category" view instead. Toggle_action() behaves different in such 
corner cases as it always installs something.
